Berbasis Problem Based Learning (PBL) Materi Persamaan Linear Satu Variabel untuk Kelas VII” ini ditulis oleh Nisa Maghfirotul Laily (2814133134) dan dibimbing oleh Sutopo, M.Pd.
Kata Kunci: Bahan Ajar, Student Worksheet, Problem Based Learning (PBL).
Proses pembelajaran matematika menjadi salah satu faktor dalam menentukan keberhasilan siswa dalam belajar. Kualitas proses pembelajaran akan mempengaruhi perkembangan potensi dan pemahaman siswa. Berkaitan dengan hal ini, maka diperlukan suatu upaya nyata untuk menggunakan pendekatan setiap kali proses pembelajaran. Salah satu upaya itu adalah mengembangkan produk
student Worksheet atau Lembar Kerja Siswa dengan pendekatan Problem Based Learning (PBL). Produk ini didesain dengan langkah-langkah pembelajaran menggunakan Problem Based Learning, uji kemampuan, tugas kelompok, dan juga evaluasi yang disertai petunjuk pengerjaan. LKS ini didesain untuk membantu siswa dalam menemukan konsep materi, khususnya materi persamaan linear satu variabel secara efektif dan efisien.
Adapun yang menjadi tujuan penelitian ini adalah (1) Untuk menghasilkan produk pengembangan bahan ajar student worksheet berbasis Problem Based Learning (PBL) menjadi produk yang valid, efektif, dan efesien (2) Untuk mengidentifikasikan efektifitas penggunaan bahan ajar student worksheet berbasis
Problem Based Learning (PBL) terhadap peningkatan kemampuan siswa menemukan konsep Persamaan Linear Satu Variabel.
Penelitian ini menggunakan metode penelitian dan pengembangan
(Research and Development). Research and Development adalah suatu proses atau langkah-langkah untuk mengembangkan suatu produk atau menyempurnakan produk yang telah ada untuk divalidasi oleh ahli yang bersangkutan dan diuji cobakan sehingga dapat dipertanggungjawabkan. Pengambilan data utama dalam penelitian ini menggunakan post test. Post test diberikan setelah produk selesai diuji cobakan. Dari hasil tes kemudian dilakukan uji perbandingan dua kelompok bebas yakni menggunakan uji independent t-test.
Adapun dalam mengembangkan produk bahan ajar ini, penulis mengacu pada rancangan Borg & Gall, namun dalam pelaksanaannya ada beberapa langkah yang tidak digunakan peneliti karena keterbatasan waktu, tenaga, dan biaya dari peneliti. Sehingga langkah penelitian dan pengembangan ini adalah: (1) Penelitian dan pengumpulan data (2) Perencanaan (3) Pengembangan draf Produk (4)Validasi ahli (5)Revisi produk (6) Uji coba lapangan.

digunakan dalam proses pembelajaran dengan presentase 77,7 % (2) hasil pengujian menunjukkan bahwa nilai t hitung > t tabel pada tingkat kepercayaan 95%.
Sehingga t tabel < t hitung atau 1,677 < 5,805. Dengan demikian, terdapat perbedaan

ABSTRACT
The thesis entitled “The Teaching Material Development Students’
Worksheet on The Basis of Problem Based Learning (PBL) in The Chapter of Linear Equation System of One Variable for The Seventh Grader” was written by Nisa Maghfirotul Laily (2814133134), advised by Sutopo, M.Pd.
Keywords: Teaching Material, Student Worksheet, Problem Based Learning The teaching and learning process of Math becomes one of the factors to decide the success of teaching Math. The quality of teaching and learning process will influence the student’s potential development and understanding. In this case, it is necessary to provide a real experiment to use an approach in every teaching and learning process. One of the experiments which can be tried is developing the material such as a student’s worksheet on the basis of Problem Based Learning. This worksheet is designed with some steps of teaching and learning process involving Problem Based Learning, test, group assignment, and also evaluation along with the guideline of its solving. This worksheet is created to help the students in finding the concept of material effectively and efficiently, especially in the chapter of linear equation system of one variable.
The objectives of this study are: (1) to make a student’s worksheet with the basis of Problem Based Learning becomes a valid, effective, and efficient student’s worksheet. (2) to know the effectiveness of using Student’s Worksheet on the basis of Problem Based Learning towards the student’s ability in finding the concept of Linear Equation system of one variable.
This study used a Research and Development method. It is a process or steps of developing a teaching material or establishing an available teaching material to be reviewed by a certain expert and tried out so that it can be accepted full responsibility for. The method of collecting data used was administering post test which was done after the student’s worksheet have been tried out. After obtaining the score of test, then the data of two groups were compared by using independent t-test.
In developing the teaching material, the researcher used the design of Borg and Gall. However, in its realization, there were some steps which were not followed due to the lack of time, energy, and the fee from the researcher. As a result, the steps of this developing student’s worksheet are: 1) research and collecting data, 2) planning, 3) developing the draft of student’s worksheet, 4) expert validity, 5) revision, 6). Try out.

analysis showed that Tcount Ttable in 95% confidence interval of the difference.
So, Ttable Tcount or 1.677 5.805. Therefore, there is a significant difference
between experimental group and controlled group. While the average value of post test experimental at 80,125 or 9,088 bether than the control class than the average value 71, 037. Thiscace proves that the Student’s Worksheet On The Basis of Problem Based Learning in improving the student’s ability in finding the concept of linear equation system of one variable.
